Answer:

197in^2

Step-by-step explanation:

5x5=25(top face)

5x5=25(left face)

9x5=45(bottom face)

6.4x5=26(right face)

Front and behind face: trapezoid area (trapezoid formula h x (a+b)/2)

(5+9)/2 x 5=7x5=35

35+35+25+25+45+25=197in^2

Answer:

Step-by-step explanation:

So let's factor!

Let's see whats this about...

$3x^{3} +15x^{2} +18x\\3x(x^{2} +5x+6)\\3x(x-1)(x+6)$

So, there you go!

sorry if this did not make sense...

What I did was essentially factor out 3x first, and then factor the second product by grouping.

Hope this Helps!

P.S. Stay Safe!
